1980 CHEVROLET CITATION octane

Downloaded from www.Manualslib.com manuals search engine Federa1 regulations require that pumps delivering unleaded gasoline be labeled
with the word UNLEADED. Only these pumps have nozzles which fit the filler
neck of your vehicle gasoline tank.
In -the United
States, Federal law also requires that gasoline octane ratings be
posted on the pumps. The octane rating shown -is an average of Research octa!1e (R) and Motor octane(M). In most parts of the United States, you should use
unleaded gasoline with an octane rating
of at least 87. However, you may use
unleaded gaSOline with an octane rating as low as 85 in thes:e high-altitude areas:
Colorado , Montana, New Mexico, Utah. Wyoming. northeastern Nevada.
southern Idaho, western South Dakota, and that part
of Texas which is directly south of New Mexico.
Using unleaded gasoline with an octane rating
lower _than staled above can cause persistent , heavy "spark knock." (''Spark knock" is a metallic rapping noise.) This
can lead to engine damage. If you detect heavy spark knock even when using
gasoline of the stated octane rating, or if you hear steady spark knock while
holding a steady speed on level roads, have your dealer correct the problem.
However. now and then you may
notice light spark knock for a short time while
accelerating or driving up hills. This is no cause for concern, because you get the
greatest
fuel economy benefit from the gasoline's octane rating when there is occasional light spark knock~ Using gasoline with a higher octane rating than that
which allows occasional spark knock is an unneceSsary expense.
Gasohol
Gasohol , a mixture of unlead ed gasoline and ethanol (grain alcohol), is
available in some areas. You may use gasohol in your vehicle, provided it
is
no more than 10% ethanol. 'Be: sure the gasohol has the same octane
ratings as stated above for unleaded gasoline. If drivability problems are
encountered because _of the use of gasohol, you should switch back to
unleaded gas oline.
NOTICE: Take care to not spill gasohol on painted surfaces. Gasohol can cause paint damage, which may not be covered under the New Vehicle Warranty.
OPERATION IN FOREIGN COUNTRIES
Your engin~ is designed to run on unleaded gasoline with the octane ratings given
under '''Fuel Requirements" above .
If you plan to drive your vehicle outside the United States and its jurisdictions
or Canada, there is a chance the gasolines available in some count,ries will not meet the needs of your engine. Low octane rated gasolines may cause engine knocking
or serious engine damage,: for which Chevrolet is not respon sible .
Using leaded gasoline
in-a vehicle equipped with a catalytic converter may cause
the converter to lose its effectiveness as an emission control.
It could also affect
the emission warranty.
If you must use leaded gasoline in a vehicle designed for
unleaded fuel, converter modification and different maintenance intervals will be
required.
For gasoline information and a maintenance schedule for the countries
in which you plan to travel, write to: Chevrolet Motor Division, Consumer
Relations Department, Detroit, Michigan 48202, (in Canada , write to General
Motors of Canada Limited. Customer Service Department , Oshawa, Ontario LlJ

When writing, please include :
• the Vehicle Identification Number and
• the countries in which you plan to travel.

IMPORTANT FACTS YOU SHOULD KNOW ABOUT FUEL
ECONOMY AND HOW TO IMPROVE IT
How you drive . where you drive and when you drive an affect how many
mileslkilometers you can get from a gallon/liter of fuel. The careful attention you give your vehicle as far as maintenance and repairs 'are concerned 'will also help fuel economy. .
Fuel Selection
Use only unle8;ded gasoline meeting the octane ratings given under "Fuel Requirements" in "Starting and Operating," Section 2 of this manual. Unleaded
gasoline must be used for the, emission control system to operate properly. Its use will also reduce spark plug fouling , exhaust system corrosio n and engine oil
deterioration . Using leaded gasoline can damage the emission control system and could result in IO$S of emission warranty coverage.
"Jackrabbit" Starts
You can save fuel (and prolong engine and tire life) by avoiding fast starts away
from lights and stop Signs. . '
Stop-And·Start Driving
Frequent stops and starts while driving cut down on your miJesper gaUon
(kilometers per liter). Plan even your short shopping trips to take advantage of
through streets to avoid traffic lights. Pace your driving like the expert drivers
to avoid unneeded stops _and braking.
Sudden Stops
Sudden stops can also waste fuel; instead of moving the vehicle , the energy of fuel
is wasted as, heal in braking. Ene'rg'y in the form of fuel is also needed to accelerate
back to driving speed~
Excessive Idling
An idling engine uses fuel, too. If you're faced with more than a minute wait, and
you're not i,n traffic, it may be better to tum, off the engine and start again later.
Lubricants
A well~lubricated vehicle means less friction between moving parts. See the
Maintenan ce Schedule folder for
the_ proper lubrication intervals.
Air Cleane.r
Your vehicle receives its power from a mixture of gasoline and air. The air enters
the engine through the air cleaner. A-dirty air cleaner element lessens engine
performance and can waste
fuel. So, it's important to -replace the air cleaner
element (filter) at required intervals. (See the Maintenance Schedule -folder.)
